Abstract
Procédés et structures associées pour la translation d'un bouchon de seringue à travers un tube sans lubrifiant, tel qu'un tube d'insertion, un cylindre de seringue ou un tube de cartouche, durant l'assemblage et/ou l'utilisation de la seringue ou de l'auto-injecteur. Le bouchon dans son état non comprimé comprend une extrémité proximale, une tige de piston s'engageant dans la cavité, et une région d'étanchéité ayant une longueur espacée de l'extrémité proximale d'une longueur de localisation d'étanchéité. La région d'étanchéité comprend au moins une nervure ayant au moins une micro-rainure à l'intérieur d'une barrière polymère, l'au moins une micro-rainure ayant une largeur initiale. Selon les procédés et structures décrits, une force de translation sollicitée vers le diamètre externe du bouchon est appliquée au bouchon en utilisant des concentrateurs de force. La force de translation avec les concentrateurs de force est suffisante pour déplacer le bouchon à travers le tube dans un état comprimé avec une réduction d'augmentation de la largeur initiale de l'au moins une micro-rainure lorsque comparée à la non-utilisation des concentrateurs de force.
